I wish to ask you about the Jak & Daxter Collection's Episode I (Jak & Daxter Precursors Legacy). When the game starts there was only the music, but no voices. I have no voices, effects and sound in the cutscenes, too?

The dongle is updated to v2.5, the CFW is 3.55 v2. The 2nd and 3rd episodes are working fine.

This happens in Ratchet and Clank All 4 One, sometimes the sound is missing in the cutscenes.
